toracocentese bilateral para alívio de paciente com derrame pleural

Bilateral thoracentesis can be a viable option for symptom relief in patients with recurrent transudative pleural effusion who have previously undergone thoracic drainage, particularly when the effusions cause significant symptoms such as dyspnea. Recurrent transudative pleural effusions, commonly due to systemic conditions like heart failure or hepatic hydrothorax, are primarily managed by addressing the underlying cause medically, including optimization of diuretics and other supportive treatments Harding et al. 2025.

Therapeutic thoracentesis under ultrasound guidance is recommended as the first-line procedural intervention for symptom relief in such patients, as it effectively evacuates pleural fluid and can be safely repeated when effusions recur Harding et al. 2025 Rijal et al. 2024. The maximum volume removed in a single thoracentesis session is commonly limited to 1 to 1.5 liters to reduce the risk of complications such as re-expansion pulmonary edema, although some evidence suggests this risk may not be strictly volume-dependent Rijal et al. 2024 Harding et al. 2025.

When pleural effusions are persistent or refractory despite optimal medical therapy, repeated therapeutic thoracenteses remain the preferred initial approach over more invasive procedures Harding et al. 2025. For select patients with frequent recurrences requiring multiple thoracenteses (more than two to three), placement of an indwelling pleural catheter (IPC) or pleurodesis may be considered, though the evidence for these interventions in transudative effusions is limited and potentially associated with complications Harding et al. 2025 Harding et al. 2025. The balance of risks and benefits should be individualized, and a multidisciplinary discussion is advised.

Regarding thoracic drainage (i.e., chest tube insertion), it is generally reserved for complicated effusions such as exudates, infections, or hemothorax and is less commonly indicated for transudative effusions unless there are exceptional circumstances like trapped lung or large symptomatic effusions refractory to thoracentesis Sorino et al. 2024. Repeated chest tube insertion for recurrent transudative effusions is not standard practice due to increased patient discomfort, infection risk, and limited additional benefit over thoracentesis. Instead, minimally invasive drainage techniques like thoracentesis are preferred for symptom control.

In summary, bilateral thoracentesis can be an effective and viable symptomatic treatment option in patients with recurrent transudative pleural effusions, including those who have had previous thoracic drainage, particularly when medical management is optimized but symptoms persist Harding et al. 2025 Rijal et al. 2024. This approach aligns with current evidence suggesting that repeated thoracentesis provides symptomatic relief with a better safety profile compared to more invasive long-term drainage methods in this patient group Harding et al. 2025.
